Shopping for marine electronics sonar navigation can feel like a choice between a ready-to-use portable fish finder and a more ambitious boat chartplotter system. This head-to-head makes that choice unusually simple: the LUCKY portable fish finder is New in Box and aimed at kayak, ice, and handheld fishing, while the Simrad NSS7 EVO3 is a non-working parts unit with a cracked screen. The real question is whether you are buying a tool to use now or a parts project.
Quick verdict
If you want a functioning sonar unit, the LUCKY FFC1108 is the clear pick. It is a complete portable device with a 2-inch LCD screen, depth indicator, transducer, and 8-hour battery life, and it runs on four AAA alkaline batteries (not included). The Simrad NSS7 EVO3 does not power on, and its touchscreen and buttons are nonresponsive. At $39.45 versus $394.94, the working fish finder is also the low end of the price range.

Where each product wins
The LUCKY wins for anyone who needs a working fish finder now. It offers a 45-degree sonar beam at 200kHz and a maximum depth rating of 328 feet, and there is no repair step before first use.
The Simrad wins in only one scenario: as a parts or repair project. The stated condition is For parts or not working, so its value depends on your ability to fix electronics or scavenge components.
Product notes
LUCKY Portable Fish Finder FFC1108
Choose this one when you want a fish finder you can carry to the water. Its 2-inch LCD has a backlight, so you can read it in low light, and the 45-degree sonar beam at 200kHz gives you a 328-foot maximum depth rating in a small package. The depth indicator and transducer are built into the same portable body, which keeps setup simple. The limitation is scale: this is a compact handheld unit, not a large fixed display. The 8-hour battery life depends on the four AAA batteries you supply, and it is built around sonar and depth finding rather than around chart plotting or other navigation functions.
Simrad NSS7 EVO3 Head Unit
This is a parts or repair purchase, not a plug-and-play display. The title points to a boat chartplotter, fishfinder, sonar, radar, and GPS head unit, but the unit has a cracked screen and does not power on, and its touchscreen and buttons are nonresponsive. A 90-day warranty is listed, but that does not turn a dead display into a working one. Its value is as a donor for someone who already owns an NSS7 EVO3 and needs internal components, or as a repair challenge for a person familiar with marine electronics. Unless you know exactly what you are fixing, the high end of the price range is hard to justify when a complete, working unit is available.
Final choice by use case
If you are heading out on a kayak, going ice fishing, or just want a portable depth sounder, buy the LUCKY FFC1108. It is the only one of these two that turns on. If you are rebuilding a Simrad NSS7 EVO3 system and specifically need a head unit chassis, screen, or other parts, the Simrad is the parts donor. For anyone who wants to use marine electronics sonar navigation on the water this season, the decision is simple: take the working portable fish finder and leave the cracked head unit for a repair bench.
